Abstract (en)
A fibrous article that generates heat upon application of electrical power is formed, for example, by joining stitch and loop yarns to form a fibrous prebody, with the loop yarn overlaying the stitch yam at a technical face and forming loops at a technical back of the fabric prebody. An electrical resistance heating element (18), e.g., in the form of conductive elements, is joined with the stitch and loop yarns in the prebody at symmetrical and/or asymmetrical spaced-apart intervals as the stitch yarn, the electrical resistance heating elements extending between opposite edge regions of the fibrous article and conductor elements (40), e.g. located along edge regions, connect the electrical resistance heating elements to a source of electrical power (52). The technical face and/or the technical back of the fabric body may have fleece formed by finishing non-conductive fibers of the stitch yarn and/or loop yarn in a manner to avoid damage to electrical conductance of the electrical resistance heating elements. Preferably, the conductive elements have the form of a conductive yarn with one or more of: a core of insulating material, an electrical resistance-heating element, e.g., about the core, and a sheath material surrounding the electrical resistance-heating element (and core). <IMAGE>
